How do you run checksum from DOS prompt?
You can do it by using "chkdsk" command.
What does P0602 Checksum Error mean?
Trouble code P0602 means:Control module programming error
IP TCP and UDP all discard a packet that arrives with a checksum error and do not attempt to notify the source Why?
they all discard it because if checksum error error it mean data is sent byother user and it forget its rout due to fault of channel if reach thereso it is not need to notify the source about this error
IP TCP and UDP all discard a packet that arrives with a checksum error and do not?
Only TCP will automatically discard a packet with a bad checksum. UDP packets have a checksum field, but it is rarely used, and then only by the application (not UDP itself)
What is the name of an error-checking procedure that uses a formula to calculate a numeric value?
checksum
IP TCP and UDP all discard a packet that arrives with a checksum error and do not attempt to notify the source?
they all discard it because if checksum error error it mean data is sent by other user and it forget its rout due to fault of channel if reach there so it is not need to notify the source about this error (Waqas Qadeer)
Why did the Checksum values change with each new request?
Every packet has a new set of error detection assigned to it, the Checksum is a part of this process. The error correction occurs in the transport layer where the ACK will fail and the receiving host will request the packet to be sent again.
Why is header checksum required in TCP?
Its used to detect an error if the packet may be mis-routed. I'm not 100% sure.
List two specific methods used on computers and networks guarantee that the data is correct at the destination?
Error checking, ie. checksum
Which statements best describes redundancy checking?
Redundancy checking is a technique used to detect errors or errors in a data transmission. It involves adding extra bits to the data to create a checksum or parity. The receiver then checks for errors by recalculating the checksum or parity and comparing it to the received value. If they do not match, an error is detected.
Do checksums change during transmission?
If the checksum did change during transmission, wouldn't that mean a transmission error occurred? Any compression or encryption in the middle of transmission affects the data at that moment, but that's the wrong time to try to calculate a checksum for comparison purposes. (Unless it is yet another layer of error checking, used after compression/encryption but before transmission, and again after reception but before decompression/decryption.)
What is checksum in the data communication?
An acronym for SUMmation CHECK. In data communications, an error-checking technique in which the number of bits in a unit of data is summed, transmitted along with the data, and checked by the receiving computer. If the sum differs, an error probably occurred in transmission and the transmission is repeated. A commonly used personal computer communications protocol called XMODEM uses the checksum technique. In some virus scanning and file integrity software checksums are calculted for every file in a directory and the results are stoed in the directory. When the program is scanningm it compares the checksum information stored in the directory with the current checksum for each scanned file. A difference in the sum may indicate that the file has been infected by a virus that doesn't leave a recognised signature.
